Biology

Atlantic Puffin (Fratercula arctica) is classified as Bird with conservation status Vulnerable. Typical weight 300–500 g (0.7–1.1 lb); lifespan around 20+ years.

Ecology

Diet: Carnivore (small fish). Habitat: Open ocean; coastal cliffs to breed. Movement and social systems reflect those pressures.

People and this species

Learn before you travel or keep related pets. Wild individuals are not toys; captive care needs species-specific husbandry.

Behavior and flight

Atlantic puffins are strong but frantic fliers, beating their small wings up to 400 times a minute to stay aloft. Those same wings double as flippers underwater, letting them swim down to catch fish. The bright colors of the bill develop for the breeding season and fade to a duller grey in winter at sea.

Diet and feeding

Puffins feed mainly on small fish such as sand eels, herring, and capelin, which they catch by diving and pursuing underwater. A puffin can hold many small fish crosswise in its bill at once, thanks to a hinged jaw and a raspy tongue, allowing it to carry a full load back to its chick. Their breeding success depends heavily on healthy fish stocks.

Habitat and breeding

Atlantic puffins spend most of the year out on the open ocean, coming ashore only to breed in large colonies on coastal cliffs and offshore islands. They nest in burrows dug into turf or among rocks, where a single chick is raised each season. Major colonies are found in Iceland, Norway, the British Isles, and eastern North America.

Conservation

The Atlantic puffin is listed as Vulnerable, with declines in parts of its range linked to overfishing of its prey, warming seas shifting fish distributions, and introduced predators on some islands. Protecting nesting islands and managing fisheries are key to their recovery. Some colonies have been re-established through dedicated restoration projects.

Research notes

Figures for atlantic puffins (Fratercula arctica) come from field studies, museum records, and conservation assessments that do not always agree on exact averages. Prefer ranges over single-point claims, and check whether a source describes wild, captive, or mixed populations.

Practical takeaways

If you encounter atlantic puffins in the wild, prioritise distance and local guidance. If you care for related domestic or captive animals, match diet and housing to species needs rather than generic pet advice. Share accurate status information (Vulnerable) when discussing conservation.
